Collagen type II is POSSIBLY SAFE when taken by mouth in doses up to 2.5 mg daily for up to 24 weeks. Itâs not clear what the side effects might be. Other collagen products, such as bovine collagen and gelatin, have caused allergic reactions.
Puffy lips are often the result of allergic reactions. These allergic reactions can lead to a condition that causes short-term swelling to occur beneath the surface of the skin, a condition known as angioedema. Puffy or swollen lips may also be caused by other conditions, such as an infection, injury, or certain hereditary conditions.
A thyroid disease and psoriosis can also cause dryness of the lips. Perleche, or angular cheilitis, can cause dryness around the mouth as can diabetes. Those with Downâs syndrome commonly have dry, chapped lips as do those with actinic cheilitis, which is caused from too much sun exposure.
